Abstract (en)
The present invention provides a dental grinding tool which is unlikely to damage gums and capable of finely shaping a formation part on which a crown is placed, and further provides a method for making the same. The dental grinding tool is made by forming a chamferred part on the end portion of a columnar metal base 10, and fixing abrasive grains 2 onto the end face 10a of the metal base 10, wherein all of the abrasive grains 2 exist inside the outer circumferential line 10d of the end face 10a of the metal base 10. Grinding is performed only by the end face 10a. When a boundary part between teeth and gums is ground, only a chamferred part 10c which have no abrasive grains comes in contact with the gums. Therefore, the damage to the gums is prevented.
